-- in llopedale, county of \Vorcester, and State of Massachusetts, haveinvented an Improvement in Filling-End Removers for Looms. of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

The invention to be hereinafter described relates to fillingreplenishing looms, and more particularly to means for removing from the100m the end of the filling that projects from the cloth selvage after areplenishing operation, that it may not be carried into the shed. As aresult of the re plenishing operation in looms of the fillingreplenishin, type. an end of filling is left PIOJQCtlDg from the clothselvage, which is liable to find its way into the shed during weaving,with the result that defects in the cloth occur. Attempts haveheretofore been made with more or less success, to prevent theoccurrence of such defects in the cloth by providing means to engage andhold the filling end, sever it at the cloth 'selvage, and then drop thefree piece of filling or withdraw it from the zone of operation of theloom parts. Such devices have caused the introduction of more lesscomplicated and delicate mechanism into the'loonr structure which ismrticularly noticeablein eliminating the spent filling end from what aretechnically known in the art-as feelerloorns. \Vith these general factsin view, the present invention aims to'simplify and produce moreellicientand reliable means for removing the filling endfroin loomsfol-lowinga replenishing operation; and,'while it is herein shown anddescribed as associated with a loom of the, ffeeler type, it is to beunder stood that the invention may be used in connection withother typesof looms and that in its true scope, the invention is not re stricted tothe details or particulars as illus trated and described, but may bevaried within the definition of the invention as pointed out by theclaims.

In the drawings: Figure 1 shows in plan view sufiicient parts of one'endof a loom provided with a good practical form of the invention to make.clearits construction and operation; Fig. 2 is a cross-sectionsubstantiall on the line 3-2 of Fig. 1, showing one form of means thatma be conveniently employed to part the filling adjacent the shuttlecontaining the filling carrier about to be abandoned, the said meansbeing shown in its normal or inoperative position; Fig. 3 is a front endview at the lower portion of a loom equipped with a suctionpump whichmay be associated with other features of the invention; Fig. 4: is asection on the line l-4, Fig. 1; and Fig. 5 is a detail showing a screenfor intercepting the filling ends in the filling end receiver.

In prior attempts to remove the filling end from a filling replenishingloom of the type wherein replenishment is effected prior to completeexhaustion of the filling inv the shuttle, a thread parting mechanismhas served to part the filling adjacent the shuttle and another partingmechanism, such as a temple thread parter, has parted the filling endadjacent the cloth 'selvage. f- Insome cases the severed filling end hasbeen held by the first-named thread parting mechanism to positionthe'filling for the "action of the temple thread parter and until thecall for 'another' operation of the re plenishing mechanism, and thenwould release the filling end'as the parting mechanisin was madeoperative. The pres.-

ent invention, when associated "in a loom of the above type,contemplates that thefilling leading from tlie snbstantially exhaustedshuttle shall be parted andthen released, and that the filling end shallpass at once into thecon'trol of a part of the present .invention, sothat when freed from the cloth se1vage,"it may be removed from the loom-As a practicalneansto this end, the inven tion aims to p'rovide' adevice preferably disposed between the cloth' selvage' and the shuttlebox'fon the same sideiof theloom,

which shall act pneumatically upon thefilliiig'end, preferably bysuction, so thatas soon as the filling of the practically ex; haustedshuttle has been parted near or ad j acentcto the shuttle, the free endthereof will pass at' once into the control of thesaid device which willhold the filling end in position for the action ie i tem'pie threadcutter and as soonas-"suc 1 aread'cirtter has acted, willcarry the nowfree piece of fillin'g away from all danger of being passed into theshedf f Any character of parting mechanism may be employed to partthefilling near or adjacent to the practically-exhausted shuttle,

vice referred to.

In the present illustrated form of parting mechanism for parting thefilling adjacent the practically-exhausted shuttle, that illustrated anddescribed in the Rhoades Patent, No. 922,511, dated May 25, 1909, isemployed, but it is to be understood, of course, that this is merelytypical of a means for parting the filling near to or adjacent thepractically exhausted shuttle; and the temple thread cutter is hereintypified as of the same general characteras that in, the Rhoades patent,although any character of thread parter that will serve to part thefilling adjacent the cloth selvage may be suitable. I i I The lay .1having the usual character of shuttle box 2 at the replenishing side ofthe loom; the breast beam 3; the transverse rock shaft .{t forcontrolling the transferring mechanism not herein illustrated; thefixedbladeo; the movable blade 6 pivoted at 7 on the arm Sand having the heel9; the pivotal support 10; the yoke 11 having the bearings 12 and 13 andthe pin 14; the jaws- 15 and 16 and associated spring 17; may all beappropriately formed, arranged, and constructed, as in the Rhoadespatent hereinbefore mentioned; and since suchdevices and theircooperative relations are clearly set forth and described in the Rhoadespatent, further elucidation herein is unnecessary. I M

When the filling end leading from the practically exhausted shuttle hasbeen severed, and the severed end clamped by the fixed and movable jawsof the thread parter, it is desirable-that this severed end portion ofthe filling be freed from the clamping action of the jaws, and to thisend the heel 9 of the movable jaw is provided with an abutment 18preferably formed as a roller,

as indicated in Fig. 2, which is adapted tov contact with a stop 19secured in appropriate position upon the breastbeam 3, as by the bolt-20, the construction being such that after the thread parter has beenmoved rearwardly andsevered the filling-adjacent the practicallyexhausted shuttle, and the jaws have been closed and hold the fillingend as set-forth in the Rhoades patent,

on the return or frontward movement of the arm 8 the abutment or roller18 will strike the stop 19' and thereby open the jaws to free the end ofthe filling for a piuipose that will, presently appear.

In order that this opening or releasing movement of the partrents ingmechanism may be appropriately timed, the stop 19 has its shank portion21 provided with a slot 22, Fig. 1, through which the bolt 20 passes,the construction being such that upon loosening the'bolt 20, the stop 19may be adjusted to cause releasing movement of the jaws 5 and .6 at thedesired time. I

The temple, which as a whole is designated 23, Fig. 1, is hereinQshownas provided with a suitable thread parter 24 adjacent the cloth selvage,but as such temple thread parter is well known to those skilled in theart and may for the purposes of the present invention be of any desiredtype, the particulars of its structure are not herein elucidated. I i

Secured in appropriate position, preferably upon the breast beam, is abracket 25, Figs. 1 and 4, provided with a sleeve or tubular bearing 26,through which projects the tube or conduit 27, said tube or conduit 27being normally held in position with its end 28 projecting towardthe'lay 1 by suitable means such as a spring 29, preferably withinthetubular bearing 26, one end of said spring bearing upon a collar 30secured to the tube or conduit 27 and the other end finding a seatagainst the endabutment 31 of said tubular bearing, substantially asindicated in Fig. 1,--the construction being such that should theshuttle be trapped in front of the tube or conduit 27 or fail to enter"the box, the end of the tube or conduit 27 may engage the shuttle asthe lay beats vupgand be moved frontwardly thereby,

air passing inwardly of the tllbGQI' conduit 27, so that when the end ofthe filling a, Fig. 1, has been parted adjacent'the practicallyexhausted shuttle, the free end of such filling may be drawn"v by theair suction into the tube or conduit 27 as indicated by the dotted linesin Fig. T; and that there after, when the filling end hasbeen parted atthe selvage of the cloth, such, piece of fill-. ing may be at onceremoved from all danger of being carried into the shed. Various expedients will suggest themselves to those skilled in, the art, forproducing the air curpassing inwardly of thetube or conduit 2 andit maybe that where a series of looms are employed, the tubes or conduits I 27of said series of looms may be connected to a single exhausting vmeans,such as a pump. In the illustrated form of the invention, however, theindividual loom is in dicated as being provided with an air pump, but itis to be understood thatthis. is typical merely of a means for producinginward air currents through the tube or conduit 27', and that individuallooms may each be provided with such or equivalent air pump, or a seriesof looms be connected to a single pump.-

Referring to Fig. 3 as illustrating an appropriate form of airexhaustion means: the crossbeam 32 of the loom has rising therefrom abracket 33 to which is appropriately secured a supporting member 34, bysuitable means such as the bolt 35, said supporting member 34 serving tosustain a cylinder 36. As a preferred means for sustaining the Ycylinder 36, the part 34 may be made as a part to surround the cylinderas indicated in Fig. 3, and be appropriately clamped thereupon by meansof a bolt ,or other securing means 37.

Rising from the bracket 33 and preferably secured thereto by the bolts38, is an arm 39 having secured thereto a bearing 40 for a shaft andband-wheel 41' carrying a crankpin 42 connected to an arm 43. The arm 43at its upper position is provided with an appropriate connection such asa swivel pin 44 to a piston rod 45 which may. reciprocate in a suitablebearing in the upper portion 46 of the arm 39, the construction beingsuch that as the pulley 41 is rotated the piston rod 45 will beappropriately reciprocated as will bereadily understood. As one meansfor imparting such movement to the pulley 41, the shaft 47, which may beeither the crank or cam shaft of the loom, is provided with a large bandwheel or pulley 48 operatively connected to the pulley 41 by anappropriate belting or band 49.

The piston rod 45 passes through a suitablepacking 50 at the top of thecylinder 36, and at its lower portion carriesan appropriate piston 51,Fig. 3. Connected to or formed upon one side of the cylinder 36 is achamber 52 having a pipe connection 53 with the flexible tube 54. At thelower portion of the cylinder 36 and-communicating with the chamber 52,is an inlet valve 55, and preferably opposite thereto is an outletvalve'56, said valves being of usual type, and being duplicated at thetop of the cylinder, although not therein shown by reason of beingcovered by the overlying parts, the construction being such that uponreciprocation of thepiston 51, air is drawn through the inlet valves 55from the chamber ,52,

- thereby creating a suction or partial vacuum in the flexible tube 54and inducing currents therein in the direction indicated in Fig. 3;

and-the air thus drawn into the cylinder is forced through the outletvalves 56', as will be readily understood. The air chamber may bevariously formed, but the particular construction herein described hasbeen found a good, practical form thereof, and as hereinbeforedescribed, each loom may be thus provided with an air pump operated inappropriate manner to produce inward currents ofair throughv theflexible tube 54,

or a single pump located in any'portion of the; building may beassociated with a plurality of looms and be appropriately driven fromany source of power. Indeed, the'con struction indicated in Fig. 3 maybe regarded as typical of such single. pump adapted for connection witha series 0 looms.

-The tube or conduit 27 has at its inner portion'a filling end receiverherein shown as a box-like device 57, Fig. 4, provided with a removablecover 58 and a screen or wire gauze 59 which will permit the passage ofair but prevent the passage of pieces of filling, or other material.

Connected to the filling end receiver 57 is the flexible tube 54, thesaid connection being preferably formed by means of a tubular projection60 at the bottom of the filling end receiver 57, as indicated in Fig.'4, though obviously other appropriate forms of connection might beemployed.

From the construction thus far described, it will be apparent that whenthe filling in a running shuttle has become practically exhausted, and achange of filling is indicated,

the filling leading from the practically exhausted shuttle will beparted adjacent thereto, and the free end thereof will immediately bedrawn into the tube or conduit 27 by the in'rushing currents of air, asindicated in dotted lines, Fig. 1. The filling end will thus bemaintained under light drawing tension by the currents of air passingthrough the tube or conduit 27 which will serve to maintain the fillingin position for the action by the temple thread cutter, and when thetemple thread cutter has parted the filling at the selvage of the cloth,the now free piece of filling will be drawn by the currents of airthrough the tube or conduit 27 and into the filling end receiver 57,where it will be intercepted by the screen or gauze 59. Obviously, thefilling ends may be readily removedfrom the filling end receiver at anytime by merely lifting the cover 58 and taking them out by hand, orotherwise. It may at times be desirable to raise the screen 59 in thefilling end receiver in order 'to clean the same; and to this end thescreen59, which may preferably be formed of wire gauze or wire cloth, isappropriately secured to the two arms 61, which may project through thebottom of the filling end receiver as iridi- -cated in Fig. 4. As anappropriate means upper portion are provided-with sleeves orenlargements 62, the lower ends of which may rest upon the walls oftheop'enings in the filling end receiver through which the arms 61project. From the construction de-,

scribed, it willbe apparent that by lifting upon the end of the arms 61.the strainer or wire gauze maybe raised in the filling 'end receiver,the filling ends removed, and then becomes free it will at once passalong with the currents of air into the conduit and be held in thisposition until the filling is parted at another point, whereupon thepiece of filling will becarried bodily by the air cur rents away fromthe weaving instrumentalities.

tion is the filling end receiver which serves to gather or receive thepieces of filhng'as they are carried away fromthe weaving1nstrumentalities by the air currents passinginto the conduit so thatall danger of pieces of filling passing into the shed is avoided.

' Where the conduit and air currents are employed to remove pieces offilling parted from the shuttle in which the filling has becomepractically exhausted, the conduit is supported with its entrancebetween the cloth selvage and shuttle box, and in such position thatwhen the lay is in forward.

position, the filling extending from the cloth selvage to the adjacentshuttle box will cross the entrance of the conduit so that the currentsof air passing into the conduit-will pass transversely ofthe filling.
